Threaded Rod Object done...

Okay, the routine that creates threaded rods in Wavefront Object format for AoI is pretty much done. I've got it creating a bound solid that works with AoI's boolean feature, though what comes out of the boolean operations can be a bit wierd at times. I'm not sure whether this sort of object is simply too complex for AoI's boolean operator routine or if the routine requires something like a right hand rule for outward facing polygons. I may have some problems with the polygon loop descriptions and got a few of them backwards.

Now I've got to throw in some parameters to dictate the pitch and depth of the threads. You can already control the number of turns of the thread and the resolution of the object.

Anybody who needs one or more of these Wavefront Objects for presentation work in AoI let me know your requirements and I will try to grind them out for you. After I get those extra parameters put in I will be going on to create an auger object for my version 2.0 filament extruder design project.
